ELEGIRIGAL BECEPTACLE.

Application filed August 13, 1925. Serial Io. 49,984.

My invention relates particularly to what are termed base receptacles and is for improvements in the device of my Patent No. 1,528,614. r v

8 The maincobject is to provide a construction in which several conductors may be connected to the same plug contacts, without the necessity of soldering, splicing or taping the conductors.

Another object is to provide a device in which conductors may be readily connected without the danger of short circuiting or grounding.

Another object is to provide a device so 16 that a plurality of wires may be readily connected or disconnected atwill.

In the accompanying drawing I have illustrated two orms of construction for accomplishing these objects. My invention contemplates the use of a body portion with especially formed recesses and terminal members adapted to receive the usual knife blade or plug terminals. In the electrical -receptacles embodying my. invention the 2 conductors are directly attached to bus bars placed on either side of the body portions and are not threaded through passages in the body member.

Fig. 1 is a face-view of the device embodying my invention.

Fig. 2 is a rear view of the same device 'showing conductors connected together by means ofbus bars located on either side of I the insulating body portion.

Fig. 3 is a side view of the same device without the conductors.

Fig. 4 is a sectional view. of the device in the plane of the line 44 of Fig. 1.

Fig. 5 is a. sectional view of the device taken in the plane of line5-5 of Fig. 1.

Fig. 6 is a face view of one form of the bus bars which are utilized in my invention. Fig. 7 is a face view of the same bus bar with attached terminals.

Fig. 7 is a transverse sectional view of v a bus bar of Figs. 6 and 7, the binding screws and contacts being omitted.

Fig. 8 is. a face view of another device embodying my invention.

Fig. 9 1s a side view of, the same device. Fig. 10 is a side view of the form of bus bar used in the device shown in Figs. 8 and 12. L

Fig. 10' is an end view and transverse section of the parts illustrated in Fig. 10.

Fig. 11 is a sectional view of the same device on a plane 5-5 of Fig. 9 and shows a bus bar and its socket member in their relation to the body member.

Fig. 12 is a rear view of the same device 60 with conductors connected to the bus bars.

The body 10 preferably formed of insulating material is provided with channels 11, and 12. It also has recesses 16 at either end to receive lug band 13 which is provided with openings 31 by which the device may be secured to the usual metal box. Screws 14 are located in recesses 36 and pass through the body 10, a flat fibre insulator 28 and the lug band 13 to nut 15 and hold together the parts through which they pass.

On either side of the body member (10) are placed bus bars 17, having a plurality of screws 18 and lugs 27 adapted to engage conductors (such as 19, 20, 21, 22) in the manner shown in Fig. 2.

The same method of connecting the conductors is also used in the single receptacle form of my invention as is bestseen in F ig. 12.

In the form of my invention shown in Figs. 1 and 7, inclusive each bar 17 has a foot offset 23 at either end of the bar for the connection of a socket member 24 which such as 19, 20, 21, 22.

A raised section or boss 33 about each screw 14 extends above the level of the remainder of the face or top portion of the insulating body 10 and pro ects through the usual face plate openings. 4

The body member 10 is also provided with an extension shield 32 extending over bus bars 17 in order to insulate the bus bars from the face plate (not shown). A face plate (not shown) is secured by screw 29 and nut 30 occupying racemes 34 and 35 of the bod portion 10.

r The ormof my invention shown in Figs.

8 to 12 inclusive is adapted to serve as a so called s' la base receptacle. It differs from the uplex type shown in Figs. 1 -7,

inclusive, in minor details of construction. For instance, the lug band 13 has an additional opening 37 to accommodate a face plate for this form, and each bus bar 39 has but one foot offset 38 and but one socket member 24.

Both forms, embodying my invention employ the flat fibrous insulator 28 which is necessary to prevent the lug band 13 from comingiinto contact with the bus bars and socket members.

By the construction as herein described it is made a very simple matter to connect a plurality of conductors by means of binding screws 18,'and lugs 27. Each device described is especially adapted to fit into the conventional metal box.

While I have described but two concrete forms embodying my invention, I wish it understood that I do not limit myself to the precise forms shown.

I claim:

1. In a device of the character described, an insulating body with recesses'opening at the side and at the back and terminal recesses extending through the body and a bus bar plate in each side recess with an attached plug socket extending into one of the terminal recesses.

2. In a device of the character described, an insulating body with recesses opening at the side and at the back and terminal recesses extending through the body and a bus bar plate in each side recess with an attached plug socket extending into one of the terminal recesses, said plug socket having three yielding contact members.

3. In a device of the character described, an insulating body with recesses, each of which opens at one side and at the back and terminal recesses extending into the bod and a bus bar plate in each side recess Wit a flange in a back recess and an attached plug socket extending into one of the terminal recesses.

4:. In a device of the character described, an insulating body with lateral recesses opening at the respective sides, and terminal recesses extendinginto the insulating body, a bus bar plate in each side recess with an attached plug socket extending into one of the terminal recesses from the rear, said plug socket having yielding contact memers.

5. In a device of the character described, having an insulating body with a terminal recess open at the back and having a plug blade entrance at the front, said body having a side recess, a bus bar in said side recess having a foot extended behind the terminal recess, a contact carried by the foot and extending into the terminal recess, an anchorage strap extending across the back of the body and secured thereto and insulated from said bus bar and said foot of said bus bar and holding the same in place.

6. In a device of the character described, having an insulating body with two terminal recesses open at the back and having two plug blade entrances at the front, said body having two side recesses, a bus bar in each of said side recesses having a foot extending beneath said insulating body, a contact carried by the foot of each of said bus bars and extending into one of the terminal recesses, an anchorage strap extending across the back of the body and secured thereto and insulated from each of said bus bars FRANCIS J.
